VENTILATOR FOR CHIMNEYS.

SPECIFICATION forming part of Letters Patent No. 697,180, dated. April8, 1902.

Application filed April 15, 1901- To (LZZ whom 2225 may concern:

Beit known that 1, CHARLES D. SM1TH,a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented a certain new and useful Ventilator for Chimneys, of which thefollowing is such a full, clear, and exact description as will enableany one skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification.

The object of my invention is to provide a ventilator for chimneys orother flues which will be simple of construction and adjustable to fluesof difierent sizes and which at the same time will effectually preventthe entrance of rain or snow into the flue.

My invention consists in certain novel features and details ofconstruction, all of which are described in the following specificationand pointed out in the claims affixed hereto.

In the accompanying drawings,which ill ustrate a form of ventilator madein accordance with my invention, Figure 1 is a view, partly in sectionand partly in elevation, of my im proved ventilator and the chimney towhich the same is attached. Fig. 2 is an enlarged section of a portionof the hanger. Fig. 3 is a bottom plan view, on an enlarged scale, of aportion of the hanger; and Fig. 4B is a top pla view of the part shownin Fig. 1.

Like marks of reference refer to similar parts in the several views ofthe drawings.

represents a tile or chimney-pot carried by a brick chimney 11.

12 is a double cone of tiling or other suitable fireproof material. Thecone 12 is secured to a spider 13 by means ofa bolt 14 and nut 15.Adjustably secured to the spider 15 are bent arms 16, preferably threein number. Each of the arms 16 is provided with a slot 17, through whichpasses a bolt 18 carried by the spider 13. Each of the bolts 18, isprovided with a nut 19. Each of the arms 16 is provided with a downwardextension 20, having an inward-projecting portion 21, terminatingadjacent to the chimney-pot 10. Carried by theinward extension 21 is a U-shaped bracket 22,adapted to embrace the top of the chimneypot 10, andthus support the ventilator. Each of the downward projections isprovided with an L-shaped bracket 23, adapted to re- Serial No. 55,881.(No model.)

ceive the sleeve 24, of tiling or other fireproof material.

In order to adjust the ventilator to chimneys of different sizes, it isonly necessary to loosen the nuts 19, when the arms 16 can be adjustedradially to bring the brackets 22 in position to fit over the edges ofthe chimney. It will be necessary to use different sizes of sleeves fordifferent sizes of chimneys. The cone 12 and the supporting parts,however, will be the same for the various sizes, and hence it will onlybe necessary for the dealer to carry assorted sizes of sleeves, all thecones and supporting parts being the same. The weight of the cone 12 andsleeve 24 is sufficient to hold the parts in place without the use ofbolts or rivets, and hence the ventilator can be detached from thechimney to give access to the same for cleaning simply by lifting theparts from the top of the chimney-pot.

It will be seen that my ventilator is very simple of construction andcan be readily adjusted to chimneys of varying size. The construction ofthe ventilator is such that the chimney is completely protected fromrain or snow by the cone 12 or 25 and that no matter in what directionthe wind may be blowing it is prevented from entering the chimney by thecombined action of the cone and sleeve.

I wish it understood that where in the specification and claims I haveused the word cone I wish to include a pyramid, as a pyramid will havethe same effect as a cone. In case a pyramid is used the sleeve in placeof being annular will be of a shape corresponding with the base of thepyramid.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of theUnit-ed States, is

1. The combination with a cone, of a plurality of radial arms adjustablysecured to said cone, brackets carried by said arms for engaging withthe top of a chimney, and brackets carried by said arms, and a sleeveremovably supported by said brackets.

2. The combination with a cone, of a spider secured to said cone, aplurality of radiallyadjustable arms attached to said spider, bracketscarried by said arms for engaging with the top of a chimney, andbrackets carried by said arms for supporting a sleeve.

3. The combination with a cone, of a spider secured to the under facethereof, a plurality .Of radial arms adjustably attached to said spider,downward extensions on said arms,

outwardly-projecting brackets on said downward extensions for supportingasleeve, and inwardly-projecting brackets alsoon said downwardextensions for engaging with the top of a chimney.

4. In a chimney-ventilator, the combination with a plurality of arms, ofa set of brackets carried by said arms for removably
